The most traveled segment in PA seems to be the I-95/US 322 concurrency (PA I-95 3 4) with 155 travelers.
I was thinking that it would be somewhere on I-81, but I-70 has segments that are much closer (153 with I-76 between 146 and 161 with the entire I-70/I-76 concurrency being between 149 and 153 travelers, and then 149 travelers on the I-70/I-79 concurrency in Washington).
In VA, I am getting VA I-95 130 133, but all of I-95 between I-295 and I-495 seems to stay consistently above 170 travelers.
For PA, we have three segments of I-95 now tied for first at 166. (
PA I-95 3 4,
PA I-95 9 10, and
PA I-95 12 13) It drops to 137 north of I-676.
In VA, first has moved south on I-95 to
VA I-95 98 104 at 190 though every segment between I-295 and I-495 looks to be above 184.
In NJ, it is on I-95 between NJTP Exits 9 (NJ 18) and 10 (I-287/NJ 440) at 186.
